@juliussneezer I am an independent contractor for several global manufacturers.
I do a better job than their direct employee versions of me.
I will come up with my own solutions, buy tools they won't, work weekends, etc.
I offer and do what they do not have.
I work a lot in hours and days and I love it.
My son worked with me for two years and is now running on his own.
As I told him, if you are tired or have something important, just don't book that week.
He can make 10k a month for two weeks/10 days a month, or he can go harder. Up to him.
I made myself essential over the years by always being available.
